Be it known that I, GEORGE G. SCIIROEDER,

. a citizen of. theUnited stat-es residing at in the District ofColumbia."

and useful Improvements whichthe following is a specification.

" wires,

- motor is provided with four trolley-arms;

each of which is adapted to come in contactwith one of the saidcurrent-wires, and each of the said trolley-arms is electrically conscribed; I

The object of the invention is to provide or track. Said car or carrieris fitted'with an electric motor which constitutes a prime; mover andfurnishes the motive power; Suspended, preferably, above and extendingparallel with each other are four current-. two of them adapted to actfor trans-- mitting the current to the motor and two'of;

them adapted to act as return-wires. The

nected with the said motor.

The prime object of the system is to so ar--. range the apparatus thatthe car may be sent: back and forth upon the cable, stopped atanydesired point, and made to travel at any desired rate of speed. Themovement of the" car in either direction is controlled by themanipulation of switches and a pole-changerlocated at either terminalstation or a way station. Each car or motor is provided witha means toprevent rocking thereof in the;

' line of travel and also to guide the car around- Said means ialsoprevents any tendency of the motor to climb or jump the: track. Thetrolley-arms are also arranged, so as to preyentlateral rocking ofthe'car.' Said trolley-arms are preferably mounted; upon a base which ispivoted to the top of;

GUI" e S the frame of the motor, so that the said Lrolley-arms mayfollow the wires while the mator 1s rounding a curve in the track.

Other objects and special constructionsfare presented, which will bepointed out inthe following description and covered in the sub'joinedclaims.

This system is especially adapted for use excavations.

This invention has relation to aerial elec-. tric transportationsystems; and it consists in the novel construction and arrangement; ofits parts, as hereinafter shown and de-'- in logging-camps and at millsfor bringing in logs from a distance and dropping them at any desiredpoint, also for removing sawed lumber and slabs and other waste from themill. It may also beused for transporting merchandise and for movingearth, &c., from In fact, its uses are too numerous'to specify,

'vantagein all instances where tion is necessary.

Fi 6 is an edge-elevation, partly in section, adeviceused to prevent rocking of the motor in the line of travel and forthe purpose of guiding the same around the curves. Fig. 7istransportaview of the disk for transmitting the current to the motor;and Fig. 9 is a side elevation,

partly in section, of the trolley-arms and their support.

The system consists of the suspended cable or track 1, above which islocated the wires 2 2 and 3 3. All of thesaid wires are parallel to eachother and parallel to said track. The electric generator 4 is located atany suitable point. The'wire connects one pole thereof with theswitch-socket 6. I The wire 7 connects the opposite pole of the saidgenerator with the switch-socket 8. The fuses 9-9 are located atsuitable points on the wires 5 and 7. v The switch 10 is adapted toenter the sockets 6-and 8, and the wire 11 connects one of the ends ofsaid switch with the socket 12, and the wire 13connect s"the otherend ofthe switchl10 with the socket 141. The wire 15 connects the wire 11 withone of the line-wires 2. I The wire 16 connects the l wire 13 with theother line-wire 2. The said line-wires 2 2 are connected throu h thetrolley-arms of the carrier with the 'fie idw of the 1 motor/18.

Figure 1 is v atransverse sectional view of the motor- Fig. 8 1s ahorizontal sectional as itmay be used to ad-' socket 22. Thepole-changer 23 (shown in 1 in the form of a switch) is adapted to beswung into either the sockets 12 and 14 or I 20 and 22. One end of theswitch constituting the pole=changer 23 is connected, by means of thewire 24, with one of the linewires 3, and the opposite end of the saidswitch 23 is connected, by means of the wire 25, with the otherline-wire 3. The rheostat 26 is located, preferably, upon the wire 25. IBoth. of the line-wires 3 3 are electrically connected, by means of thetrolley-arms of the carrier, with the armature 27 or" the motor 18. hearmature 27 is held in a fixed position a ainst rotation, aswill behereinafter eX- pi ained, while the field 17 rotates about the saidarmature.

Presuming that the parts are in the positions as indicated in Fig. 2,the current starts 1 from the generator 4, passes along the wire I 5 tothe socket 6, then through the switch along the wire 11, then along wiret0 the inner line-wire 2, thence through the arinature 17 along theouter line-wire 2, thence along wire 16 to the wire 13, then through Iswitch 10 along wire 7 back to the. opposite i pole of the generator 4.At the same time I the current passes from wire 13, through socket 12and along wire 19, to socket 20, j thence along one en of the switch 23to wire I 25, t ence along the said wire 25, through rheostat26, to theinner line-wire 3, thence to I the armature 27, thence along the outerlinewire 3, thence of the along the cross-wire 21 to socket back to thegenerator over the wire 13 and its connections. By su plying the currentto the armature and ti along wire 24 to the other end switch, thence tosocket 22, thence 14, thence 1e field as above de-.

l scribed the said armature is rotated in one; direction. To change thedirection ot rota- I tion of the armature, the switch 23 is disengagedfrom the sockets and 22 and turned i into the sockets 12 and 14. hecurrent ,I then passes from the generator 1 to the field l 17, as abovedescribed. 'hile the course of i the current through the armature 27 isre i versed that is, the current passes from the 5 socket 12 along oneend ofthe switch 23, then 5 along wire 21 to the outer line-wire 3,thence through the armature 27, thence back along the inner line-wire 3,thence along wire 25, through the rheostat 26, to the opposite end T ofthe switch 23, thence along said switch to i the socket 14, thence alongthe wire 13 and 5 its connections back to the generator 4. Thus therotation of the field 17 about the ar- 1 mature 27 is reversed. To outoff the current at any desired point, the switch 10 is disconnected fromthe sockets 6 and 8, and thus the motor is stopped. The switches 10 and23 may be included in one instrument, as I may also the rheostat 26,such an instru-, ment being commonly known as a startingbox. At anyevent the switches 10 and 23 t the upper portion of the extendingportion A -19, the tension of and the rheosta-t 26 should be locatednear each other, so as to be operated by oneperson.

The motor 18 consists of an outer shell or easing, within which thearmature 27 and the field 17 is housed. Around the periphery of the saidcasing extends a grooved annulus 28, which is adapted to 11m upon thecabie 1. The disk 29 is so located as to rotatewith the casing of themotor 18. The outer face of the said disk is provided with metal rings30, 31, 32, and The outer ring 30 is connected, by means of the wire 34,with one of the brushes of the armature, and the ring 31 is connected.by means of the Wire 36, with the other brush of the said armature. Thering 32 is connected, by means of the wire 37, with one of the fields ofthe mo tor, the wire 38 connecting the fields together and the Wire 39connec'ng one of the said fields with the ring 33. Thus the electricalconnections through the 1 Mar are cornpleted. The trolley-arms are eachprovided at their upper ds with a troileywheel 41, and the wires '22extend down from the said trolley-wheels with the brushes or (2 ends ofwhich bear age 5 32, and The lower ends ti arms 40 are pivoted to crov1s.. The said trolley-arms at their pivotai poin i are in alinenientwitheach other; but two'ot the said trolley-arms extend in one direction andbear against the inner line-wanes 2 and 3, and the two remainingtrolley-arms extend back in substantially an opposite direction 1 andbear against the outer line-wires 2 and The crosspieee 4-1 is pivoted atits middle t frame 15, the pivoting-bolt 46 having a ver cal ringthrough which the wires 42 42 pass. (1 a. frame 45 3 provided with a.t'orwardly and rearwardly 4.7, at the inner ends of which are securedthe vertical extending shafts 48. The guide-whecls are journaled at thelower ends of the shaft 48 and are adapted to run upon the cable 1. Thecoil-springs 50 are interposed between the lower ends oi the portions t?and a suitable collar on the shaft 43 above the Wheels said.coil-springs being to force the wheels 49 away from the lower ends ofthe portions -17. The side portions 51 and 52 extend down tron'i 51being secured at its lower end to one end of the shaft of the motor 18,whilethe por tion 52 extends down on the opposite side of the motor 18and is (?OIiI1t3Ct-O(l.tO the opposite end of the shaft thereof andextends down, forming the shank 53. to which the load 54 may beattached.

it will thus be seen that as the carrier moves back and forth the wheels4.9 their connections will have a tendency to prc-- vent rocking or themotor in theline of travel. The said wheels will aiso guide the motor inthe top 4-5, the portion I around curves and have a tendency to p195iem;- any inclination on the partaof the itiQtortfrom riding up above'thecable 1. The swivel connection between the cross- 5 supporting the,lower ends of the trolleyarms -and the top-piece eta the framecompensate for any change in direction which might occur between the.current-wires notwithstanding any such lack of 10 alinement, thetrolley-arms 40 being pivmted insalinement attheir lower ends to thecrossapiece 44 andextending up and in front andtbehind a perpendicularerected from the ceiitr'o f the motor 18, having a tendency'to r5 "ventany lateral rocking of the motor or m'loadcarried by the same.
